Background

The existing air conditioner and refrigerator compressor motors are aluminum enameled wire motors, and the lead-out wire assembly used in the motors is generally a multi-strand copper wire. When an aluminum wire and a multi-strand copper wire are connected, oxidation is easily generated in the use process. Because the conductivity of aluminum is different from that of copper, the heat conduction current is inconsistent, and conductive media are lost when the aluminum is electrified; in a naked environment, oxidation-reduction reaction is easy to occur to form a primary battery, so that the oxidation of aluminum is accelerated, and obviously, the service life of the motor is influenced.

In the figure: the structure comprises a copper wire bundle 1, a copper wire 100, a tin-plated layer 101, an insulating layer 102, an enameled aluminum wire 2, a wiring terminal 3, a protective sleeve 4, a stator core 5, a coil 6 and a leading-out wire assembly 7.

Detailed Description

In the description of the present invention, it is to be understood that the terms "one end", "the other end", "the outside", "upper", "inside", "horizontal", "coaxial", "central", "end", "length", "outer end", etc. indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.

The present invention will be further explained with reference to the accompanying drawings.

Example 1

Referring to fig. 1-4, a leading-out wire assembly includes a copper wire bundle 1, an enameled aluminum wire 2 and a connecting terminal 3, wherein the copper wire bundle 1 and the enameled aluminum wire 2 are arranged side by side, the connecting terminal 3 is sleeved on an end of the copper wire bundle 1 and an end of the enameled aluminum wire 2, and each strand of copper wire 100 in the copper wire bundle 1 is covered by a tin-plated layer 101. The copper wire harness 1, the enameled aluminum wire 2 and the wiring terminal 3 form a lead-out wire assembly of the motor coil.

It can be understood, in above-mentioned technical scheme, the utility model discloses set up tin coating 101 on the every copper wire of lead-out wire subassembly, stop copper, aluminium wire direct connection, cause oxidation reaction, can effectively prolong motor life.

With continued reference to fig. 2, the exterior of the copper wire harness 1 is covered with an insulating layer 102, and the end portion of the copper wire harness 1 is exposed from the insulating layer 102, and the exposed portion is connected to the connection terminal 3.

Further, due to the presence of the insulating layer 102, there is no chance of the portion of each copper wire 100 covered by the insulating layer 102 coming into contact with the enameled aluminum wire 2, and therefore, the portion may be selected not to be plated with tin, thereby simplifying the plating process and material cost.

With continued reference to fig. 1, the terminal 3 is sheathed with a protective sheath 4, preferably a heat shrinkable sleeve, which is mounted on the terminal 3 by a heat shrinking process.

Wherein, the length of protective sheath 4 is greater than the length of binding post 3, and protective sheath 4 extends to on partial insulating layer 102 and the enameled aluminum wire 2, and the protection scope is wider.

Example 2

Referring to fig. 5, a stator of an electric motor includes a stator core 5 and a coil 6 disposed on the stator core 5, wherein the coil 6 is disposed with an outgoing line assembly 7 as described in embodiment 1.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention.
